PLAlTlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 229,423, dated June 29,1880.

Application filed January 3, 1880.

To all whom it may concern Be it known that I, GEORGE W. KENDALL, of St.Albans, in the county of Franklin and State of Vermont, have inventedcertain new andusefullmprovementsin Plaiting-Machines; and I do herebydeclare that the followingis a full, clear, and exact description of theconstruction and operation of the same, reference being had to theannexed drawings, makinga part of this specification, and to the lettersand figures of reference marked thereon.

Figure 1 of the drawings is a representation of a vertical transversecentral section of my plaiting-machine, and Fig. 2 is a perspective viewof the yoke-frame.

The main frame of my improved plaitingmachine is essentially composed ofthe two sides A, (only one of which is shown,) rigidly connectedtogether by cross-bars B. The plaiting-knife O is hinged to the ends ofa yokeshaped frame, which, in turn, is pivoted to the sides of the mainframe. The knife and its supporting yoke-frame C have a common vibratorymovement, while the knife has an independent oscillatory motion upon itshinged bearings, such movement being controlled by means of a rod, D,which passes through an opening in the top portion of the vibratoryyoke, and is linked at its lower end to the knife. This rod is providedwith a knob, d, at its upper end, by means of which it may beconveniently manipulated and the knife raised or lowered upon its hingedbearings. The yoke U is pivoted in such position that the knife which itcarries will be somewhat above the level of a shelf, E, and also nearertoward the center of the machine than the same, so as to rest upon acylinder or drum, F, when it is not raised by the rod D. This drum issuspended within the main frame by means of an endless belt, E, whichpasses around a portion of the same and sustains it against an upperroller, G, the rotation of which causes the travel of the endless bandand the consequent rotation of the drum. This endless band, which iscomposed of any suitable fabric, passes around the roller G at the topof the main frame, and also around a roller, H, which is journaled inthe sides of the frame below the shelf E. After passing around therollers G and H and that portion of the cylinder-face which isintermediate of the said two rollers, the belt passes around threerollers, I I, which are journaled in the sides of the main frame, asshown. These last three rollers serve merely to guide the belt as itreturns from the lower roller, H, to the upper roller, G. This roller Gis provided with a ratchetwheel, G, and upon the axis of said roller isloosely mounted an arm, K, carrying a pawl, L, which takes into theratchet of the roller. A connecting-rod, M, connects the arm K with thevibratin g yoke C, so that as the yoke is vibrated the arm K will beoscillated upon its axis, and hence the roller G be rotated during theforward movement of the pawl.

The yoke is formed with a series of holes, N, in order that the throw ofthe arm and pawl may be determined by the position of the connecting-rodin said series.

0 designates a slotted stop-plate, which is arranged upon the side ofthe main frame by means of a pin, 0, which passes through the slot ofthe said plate. As the yoke is vibrated so as to swing the knife whichit carries away from the line of juncture between the roll G and thecylinder the lower end of one of the yoke-arms strikes against the stop0, which thus limits its extent of vibration. This arrangementdetermines the number of teeth over which the pawl will ride during itsbackward movement, and hence also determines the intervals of theplaits. This stop may be adjusted so as to regulate these intervals byloosening the screw and shifting the stop-plate.

P designates a stop, which is arranged so that when the knife is thrownforward the yoke will strike against it, thus limiting the extent towhich the knife will pass between the cylinder and the upper roller.

The sides of the main frame are formed with open doorways Q, throughwhich the lamp B may be passed in and out of the cylinder F. A shelf, S,extends from side to side of the main frame, so as to constitute asupport for the lamp, the said shelf passing through the cylinder, asshown.

T designates a bed-plate upon the shelf S, said plate being formed withguides at its sides for the flanges U at the base of the lamp-body.

In operating the machine the fabric to be plaited will be passed alongthe shelf E toward the line of contact between the cylinder and the bandsurrounding the upper roll. The knife is then operated so as to takehold of the fabric by vibrating the yoke, and as such operation iscontinued the cloth is plaited and carried round by the rotation of thecylinder and the travel of the band or belt. As soon as the plaiting hasbeen completed the lamp will be withdrawn from the cylinder, to preventundue heating thereof and consequent scorching of the goods. By nowallowing the i plaited fabric to remain for awhile around the cylinder,endless belt, ratchet upon the roller 25 G, pawl, and connecting-rod,substantially as set forth.

2. Thedrum or cylinder F,snpported against the upper roller by means ofthe endless belt, substantially as set forth.

3. The main frame, with doors for passing the lamp into and out of thecylinder, and the shelf for supporting the lamp, arranged to extendthrough the cylinder, in combination with the endless belt, cylinder,and upper feed-roll, substantially as set forth.

4. The herein-described arrangement of to tary heating-cylinder, endlessbelt, upper feedroll, vibratory knife, stops, and. shelf, substantiallyas set forth. 4.0

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

GEORGE W. KENDALL.
